Location: Soybean/maize Germplasm, Pathology, and Genetics Research
Project Number: 5012-21000-029-003-N
Project Type: Non-Funded Cooperative Agreement
Start Date: Jan 1, 2017
End Date: Jul 31, 2021
Objective:
To further advance soybean germplasm generated from crosses of Glycine tomentella and Glycine max and to make such Germplasm available for research and breeding purposes.
Approach:
G. tomentella-derived lines will be used for a variety of research objectives. Lines have been developed that yield more than the soybean parent and these lines will be used to identify the specific genetic contribution from the G. tomentella parent that enhance yield and the yield enhancing genes will be transferred into high-yielding experimental lines and cultivars. Lines with resistance to soybean rust and phytophthora root rot have been identified and the genes responsible for the resistance will be determined. Lines will continue to be screened for new disease resistance and abiotic stress tolerance. Genetic aberrations have been found in lines that revert from 2n=42 chromosomes to 2n=40 chromosomes and these changes are being documented and the mechanisms behind these changes will be determined In addition, the effects of G. tomentella cytoplasm on seed yield and other plant traits will be studied.
Third-party access to “Material” and “ARS Material” will be accomplished using agreements that are appropriate for the purpose.
